Officers were called shortly after 11:40 p.m. Saturday to the 1500 block of Marshall Street, where Sara Harris, 45, was found inside a home suffering from multiple stab wounds to her torso and back. She was taken to Shock Trauma, where she died.

Police said Monday that William Thornsberry, 57, was arrested in the case and charged with murder and various weapons violations.

Witnesses told police they saw Thornsberry talking on a cellphone in front of the house and that they heard him say the word "kill" in his conversation.

During questioning, investigators said that Thornsberry told officers the victim was his fiancée and that she had been drinking heavily that night and tried to fight him. Thornsberry told police that he left the house but came back 10 minutes later, and when he did, he found Harris holding a knife.

According to charging documents, Thornsberry said he tried to get the knife from her, and while doing so, she was stabbed five times. Thornsberry said he then tried to clean the knife in the kitchen sink, where detectives later found it.

Charging documents said that Thornsberry didn't call police but instead had a friend call 911 about 40 minutes after the incident. Police said the call came in as a report for an attempted suicide.

Charging documents showed that Thornsberry had blood on him and a cut, which he said was due to a self-inflicted scratch.

A medical examiner ruled Harris' death a homicide, which led to Thornsberry's arrest. He's currently being held without bail at Central Booking.
